Only IRQs that have enable_irq_wake() called on them can wake the system from sleep or after it has been shut down. Currently, the RTC alarm can only wake the system from sleep. Run the suspend callback to arm the IRQ during the shutdown process, so the RTC alarm also works after shutdown. Signed-off-by: Samuel Holland <samuel@sholland.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
